Hamilton-Jacobi equation

[′ham·əl·tən jə′kō·bē i‚kwā·zhən]
(mathematics)
A particular partial differential equation useful in studying certain systems of ordinary equations arising in the calculus of variations, dynamics, and optics: H (q1, …, qn , ∂φ/∂ q1, …, ∂φ/∂ qn , t) + ∂φ/∂ t = 0, where q1, …, qn are generalized coordinates, t is the time coordinate, H is the Hamiltonian function, and φ is a function that generates a transformation by means of which the generalized coordinates and momenta may be expressed in terms of new generalized coordinates and momenta which are constants of motion.
